Planning my first tank - 60p Any advice?
Filter is fine, the next size up won't hurt.
Light will need to be 6-8" off tank to evenly illuminate 12" across. I run 2x ray 2 DS on 24", and right against tank, there is definitely light gap between evenly spaced strips when directly on tank.
Do yourself a favor and splurge on a whole CO2 assembly (nice 5lbtank, GLA reg and large disk diffusor my recommendations).
It scales up to any other tank in future, you can split the feed to handle multi-tanks from one reg, and most reliable source of carbon. Just do it.
